Abstract

An acrylic polymer having a multilayer structure and comprising an innermost layer (A) of a polymer prepared from a C1-4 alkyl methacrylate, a C1-8 alkyl acrylate or the like, an intermediate layer (B) of a polymer prepared from a C1-8 alkyl acrylate, an aromatic vinyl monomer or the like, and an outermost layer (C) of a polymer prepared from a C1-4 alkyl methacrylate, a C1-8 alkyl acrylate or the like, wherein an average value of a complete coverage defined as '[minimum thickness of intermediate layer maximum thickness of intermediate layer] x 100' is not less than 30 %; and a methacrylic resin composition containing the same. The acrylic polymer having a multilayer structure can improve the falling-ball/falling-weight strengths, impact whitening resistance, transparency, and other properties of the methacrylic resin composition.
